i get tinnitis easily and love these, ever since i started wearing them, no more tinnitis after shows: https://www.amazon.com/LiveMus-HearSafe-Silicone-Triple-Noise-Cancelling/dp/B00H2F87I8/ref=sr_1_50?ie=UTF8&qid=1492450738&sr=8-50-spons&keywords=ear%2Bbuds%2Bfor%2Bmusicians&th=1
Just do yourself a favor, unless you have no other option, dont use foam earplugs. They completely muffle all the high end and sound terrible. I would recommend these earplugs. It comes with two pairs. 15db and 25db reduction.
I've also used these a lot.
These are the ones I use, I love the little carry case I can put on my keychain.

You also get 2 sets, one that blocks out more than the other.
